**Christiaan**, Monday, January 28, 2008 at 7:09amTorque is calculated by the formula:

t=r.F.sin(a) where a is the angle between the rod and the force acting on the rod(=25°),

r is the distance from the force to the pivot point(which is 1m),

and F is the gravity force acting on the ball(=m.g = 0.85kg.10m/sē =8.5 N)

So, the torque equals:

t=1m . 8,5N . sin(25°) = 3,59 Nm
